ALARM-BELL FOR BICYCLES.

SPECIFICATION forming part of Letters Patent No. 622,440, dated April 4, 1899.

Application filed May 10, 1898, Serial No. 680,280. (No model.)

To all whom it may concern.-

Be it known that 1,-HERMANN BRANDLI, of Jersey City Heights, county of Hudson, and State of New Jersey, have invented certain new and useful Improvements in Alarm-Bells for Bicycles, of which the following is a full, clear, and exact specification, reference being had to the accompanying drawings,wherein Figure 1 is a perspective view of my improved bell-bracket; Fig. 2, a sectional view of the same with the bell set in position; Fig.

3, a bottom View of the bell; Fig; 4, an elevation of the bell-movement; Fig. 5, a sectional view on lines 5 5, indicated in Fig. 6; Fig. 6, a bottom view of the bell-bracket. Figs. 7 and 8 are elevations showing my improved bicycle-bell attached to the frame of the bicycle. Fig. 9 is an enlarged detail view showing the construction of the operating mechanism for starting the bell combined with the brake.

My invention relates to bicycle appliances; and it consists of the hereinafter-described construction of a bicycle-bell and of the bracket for mounting the same in such position on the frame that the movement of the bell may be operated by the tire of the wheel and of the construction of mechanism whereby the bell may be operated by the brake-lever simultaneously with the brake.

The bell proper consists of the globe 1, provided with an inwardly-projecting abutment 2,and of the movement, which comprises shaft 3, friction-wheel 4, set on one end of the shaft, bars 5 and 6, mounted transversely upon the shaft 3, and oscillatinghammers 7, pivoted one to each end of the bars 5 andt by pivots 8. Strikers 7 are held between the bars 6 and washers 9, and they swing on the pivots, so that when the shaft 3 is rapidly rotated the projections or abutments 10 of these strikers are thrown outwardly and strike against the projections or abutments 2, and thereby produce the sound. The peculiar configuration of the strikers '7 is shown in Fig. 3 in plan and in Fig. 4 in side elevation. They are made in the shape of cams, the abutments 10 being the farthest projecting parts from the center, as represented by pin 8. The circumference of these strikers is so shaped that when receded they may pass along the abutment 2 of the bell without striking and ,again,

so that when striking against the abutment 1 is screwed thereto by screw 14. Washers 15, set on the screw 14. between the bell globe 1 and the arch 13, serve for the adj ustment of the position of the bell-globe within the arch. Bar 12 and arch 13 compose the frame of the bell.

The bracket for affixing the bell to the frame of the bicycle consists of the bar 16, the forked arm 17, and arch 18, which is fitted upon the flanged side bars of the arm 17 and forms, together with them, a clamp held together by screws 19. The longitudinal edges of bar 16 are turned at right angle to its plane and form ways 20, on which the bar 12 rests and slides to and fro. Bars 16 and 12 are fas toned together by screws 21, one of which is screwed in each of the bars and passes through a slot 23 and 24, respectively, provided in the other bar. Washers 22, set between the heads of the screws 21 and the surfaces of the bars 12 and 16, respectively, are provided to facilitate a smooth sliding of the parts. Slot 25 in bar 16 provides a passage for the tube 11 when the bell-frame is shifted in its position relatively to the bracket. Ahooked pin 26 is fastened in the bar 16, and a similar pin 27 is fastened ,in the washer 22 of the screw 21, screwed in the bar 12. A spiral spring 28 is attached to the pins 26 and 27, so as to draw them together. This spring holds the bell in the position shown in Fig.2, the tube 11 being then at the downwardend of the slot 25. By pulling the bar 12 in the direction indicated by the arrow in Fig. 2 the position of the bellframe in relation to the bar 16 is shifted. This is done for the purpose of bringing the friction-wheel l in contact with the tire, as shown in Fig. 9, and when the pull is released spring 28 contracting draws the frame of the bell again in its normal position, thereby withdrawing friction-wheel 4 from the tire.

The manner of affixing the bell to the frame of the bicycle is illustrated in Figs. 7, 8, and 9. Bracket 17 is clamped by arch 18 and screws 19 to side bar 29 of the fork in such position that the friction-wheel 4 will stand inwardly and near below the tire 30 of the wheel of the bicycle when the bell-frame is in its normal position.

The bell-frame (composed of bar 12 and arch 13, as explained above) is connected by means of wire 31 to lever 32, fulcrumed between the side bars of the bracket 33, which is rigidly affixed to the handle-bar 34 by collar 35. Lever 32 is provided with a thumbpiece 36, projecting inwardly from the handlebar. By pressing upon this thumb-piece 36 of the lever 32 the bell-frame, and with it also the friction-wheel 4, is lifted upwardly into the position indicated in dotted lines in Fig. 9, whereby the friction-wheel 4 comes into contact with the tire 30 and is set thereby in rapid rotary motion. This motion is imparted, as explained above, to the movement of the bell and causes the hammers 7 to strike with their abutments 10 against the abutment 2 of the bell in rapid succession and to produce thereby the ringing sound. \Vhen the pressure upon the terminal 36 of the lever is released, the spring 28 draws the bellframe downwardly, and thereby also withdraws the wheel 4 from contact with the tire 30 and the ringing of the bell ceases.

In Figs. 7 and 9 I have shown a device for operating the bell simultaneously with the brake. This arrangement is devised to enable the rider'to operate the bell on such occasions where he is required to apply the brake simultaneously with ringing the bell. The device consists in the collar 37, secured to the fork-stem 38, double-armed lever 39, fulcrumed on screw-bolt 40, collar 41, rigidly secured to brake-rod 42, and ball 43, secured to the wire 31. Arm 44.0f the lever 39 is bifurcated, and the wire 31 passes through the slot, which, however, is only wide enough to permit the wire to pass through and not the ball 43. Arm 45 of the lever 39 is extended in front of the brake-rod 42 and below the collar 41. This arm is provided with an upwardly-projecting tooth 46, engaging with the collar. \Vhen the brake is applied, rod 42 is moved downwardly by the lever 47, as indicated in dotted lines in Fig. 9. Ring 41 presses upon the arm- 45 of the lever 39, moving the other arm 44 of the lever upwardly. Ball 43 cannot pass through the slot, and thus the lever pulls the wire 31 and the bell-frame upwardly and, bringing frictionwheel 4 in contact with the tire 30, causes the bell to ring in the manner as described above.

I am aware that bicycle-bells mounted in movable frames adapted to be operated by a friction-wheel brought in' contact with the tire of the bicycle were known heretofore;

but my invention differs from those devices in that these bells require intermediate gears fol-transmitting the motion from the frictionwheel to the movement of the bell, and consequently besides being more complicated in construction and requiring many more parts than my improved bell described above they require also a safe incasing of the gearing parts, and, in fact, of the whole device, to prevent their becoming clogged by dust and unserviceable.

My improved bell is greatly simplified in construction and does not require practically any casing at all, the only part oiled being safely preserved in the tube 11. There is practically no part that could be rendered inoperative by becoming clogged with dust or otherwise.

Owing to its simplicity of construction, my improved bicycle-bell can be manufactured very cheaply and is easily applicable to any bicycle or similar vehicle now in use.
